DISINFECTOR.

To all whom t may concern:

Be it known that I, HARRY L. SGHELLEN- BERG, a citizen of the UnitedStates, residing at Detroit, in the county of l/Vayne and State ofMichigan, have invented certain new and useful Improvements inDisinfectors, of which the following is a specification.

This invention relates to disinfectors for water-closets and othersanitary devices, and its object is to provide suitable means forholding and automatically discharging quantities of disinfectant and toso construct and arrange said means that the operation of the same willbe automatically controlled by the water supply for said devices, todischarge a predetermined quantity of the disinfectant into the trap,bowl, or other device to be disinfected after each iiushing operationtakes place.

A further object of the invention is to provide certain other new anduseful features in the construction arrangement and combination ofparts, all as hereinafter more fully described reference being had tothe accompanying drawing in which,

Figure l is a front elevation of a flushing tank with the front brokenaway to show the interior and a device embodying this invention in placetherein. Fig. 2 is a cross section of the same on the line m-m of Fig.1; Fig. 3 is a perspective view of the holder showing the same inlongitudinal section; Fig. l is a sectional detail of the dischargeslide; and Fig. 5 is a detail illustrating a modified construction.

As shown in the drawings 1 represents the outer rectangular casing of anordinary flush tank, and 2 the inner metal lining or tank of the same.

3 is the water supply pipe entering the bottom of the tank near one end,and t is a valve to control the iniiow of the water which valve may beof any suitable construction and operated in the usual manner by meansof a float 5 attached to the end of a lever arm 6 acting upon the valveto close the same when the float is lifted by the rise of water in thetank.

7 is a flush pipe leading to the bowl or other device to be flushed, and8 is a valve of the ordinary construction controlling the outflow ofwater from the tank into the flush pipe. This valve 8 is provided with afloat 9 so that when the valve is lifted by means of the valve rod 10attached to the Specification of Letters Patent.

end of the lever 11 pivoted to the side of the tank and operated in theusual manner by means of a rod 12 connected to a push button 13 on theoutside of the tank, said valve will be held from its seat by said floatuntil the water has escaped from the tank. The overow pipe 14 isconnected to the flush pipe below the valve 8 and an after-fill tube 15is connected at one end with the casing of the inlet valve l and at itsupper end discharges into the upper end of the overiiow pipe, saidoveriow and afterfill being constructed and arranged to operate in theusual manner to supply the bowl with a quantity of water after it hasbeen iiushed out by the volume of water in the tank.

A small receptacle forming a holder 16 for disinfectant material issupported in any suitable manner in the upper part of the flush tank.The disinfectant contained in this holder is preferably made up in theform of small balls 17, and to insure the movement of these balls towardthe discharge end of the holder, said holder is made with asemi-circular bottom 18 having a depression or groove 19 along itslongitudinal center line. This bottom is also preferably made at aslight incline toward its lower end at which end is a discharge openingin the bottom of the groove.

A guide casting 20 is secured to the bottom of the tank and surroundsthree sides of the discharge opening to form a guideway for a verticallyreciprocatory discharge slide 21 which is provided with a transversehole 22 of a diameter just suflicient to receive one of the disinfectantballs. This slide lies against the end wall of the holder in which wallis a vertical slot 23 to receive a tongue 24C on the slide. An operatinglever 25 is pivotally attached at one end to the end of the holder andthrough a longitudinal slot in this lever is inserted a screw 26engaging a screw threaded opening in the upper end of the dischargeslide. The slide is thus guided at its lower end in the casting 20, andat its upper end by the tongue 21 engaging the slot 23. The free end ofsaid lever 25 is connected by means of a rod 29 to the lever 11 and thesaid lever 25 is moved thereby, such a distance that the slide will bemoved downward suilciently to expose the end of the hole 22 below theend wall of the holder, and when the slide is raised to position shownin Fig. 3 to receive a ball in its hole 22 and the slide is then moveddownward,

the ball will roll out at the opposite end of the hole into a suitabletrough 27 secured at one end of the casting 20, and be discharged intothe upper open end of the overflow pipe 14. The slide moving up and downwithin the casing at the lower end of the groove 19 will agitate theballs and insure the entrance of a ball into the hole therein at eachreciprocation of the slide. In this construction the full benefit of thedisinfectant and the very best results are secured by ejecting aquantity of disinfectant which is in the proper proportion to the waterin which it is placed, or the after-lill water which stands in the bowland trap or other part flushed until the neXt flushing operation, andthus thoroughly disinfects the parts.

In a construction where the flush tank is periodically emptied by meansof a siphon or other automatic device, the operating lever 25 of thedischarge slide is actuated as shown in Fig. 5, by means of the float 28attached thereto, and the holder may be arranged to discharge thedisinfectant directly into the tank, as shown in said figure, or it maybe arranged to discharge into any other convenient part of the flushingsystem.

While I have shown my invention as applied to flushing systems of aparticular class, namely those embodying a fiushing tank, I do not wishto limit myself to its application to such systems, as the invention mayobviously be applied to fiushing systems other than those of the classshown.

Having thus fully described my invention what I claim is:
